A multi-element spray delivery system for targeted delivery of product from aerosol spray cans comprising an aerosol can button having a short connector tube connecting to a removable extension tube. The system optionally includes a spray discharge limiter, and a sealing tip cap that fits over either the button connector tube or the extension tube. The selective combined use of these components permits targeted delivery of aerosolized product, including lubricants, paint, personal care products, food products, insulation and caulks, herbicides, insecticides or compressed air for more efficient and effective delivery as and where needed with reduction in waste and overspray. An extension tube keeper system is included for convenient storage of the extension tube on the can after use. The component system is also provided in a kit form either by the OEM producer of the aerosol product along with the new can, or as an after-market product.

The invention claimed is: 1. In an aerosol can spray delivery system of the standard type having a two-part spray button comprising: a pressurized aerosol can having a generally planar top cap in which is mounted a product release valve assembly, said top cap being secured to a top dome of said can at a rolled inner edge of said dome, said valve communicating internal of the can with a dip tube and communicating at an outlet end with a standard two-part finger-actuatable spray button of the type including a product passage therein in communication with the outlet end of said valve, and a small diameter lateral metering orifice disposed recessed in a lateral bore in the sidewall of said button, said metering orifice communicating with said button product passage but does not extend beyond the sidewall of said button. the improvement in said aerosol can spray delivery system comprising replacement of said standard two-part spray button with an improved button comprising: a) a spray button selected from a male button and a female button having a lateral bore communicating with a vertical central product passage bore; b) a short connector tube having a central bore and a first, inner end permanently secured in said lateral bore of said spray button in place of said standard button metering orifice, said connector tube terminates in an outer, second end and said connector tube includes a restriction disposed at one end therein defining a spray metering orifice; c) said bore of said connector tube is in communication with said button product passage; d) said connector tube has a length in the range of from about 쩌" to about 2"; e) an extension tube straw having a first, belled and flared end and a second outer end, said first belled and flared end is sized to receivingly engage and be securely retained on said connector tube outer end to provide remote, targeted delivery of product spray, produced from said connector tube, to and from the outer end of said extension tube without overspray, and said second outer end of said extension tube straw does not have a restricted orifice therein; and f) so that said connector tube is secured in said spray button lateral bore with its central bore opening and metering orifice coordinated with the button product passage to provide continuous flow of product from the can through the connector tube when the button is actuated to produce spray, said connector tube being sized for diameter and length to receivingly engage said extension tube straw for confined delivery of a controlled amount of product spray produced by said connector tube to a user-desired target without overspray. 2. An improved aerosol can spray delivery system as in claim 1 which includes a removable cap that sealingly fits over said connector tube outer end and said extension tube outer end to seal the tubes when not in use. 3. An improved aerosol can spray delivery system as in claim 1 which includes an extension tube keeper system comprising a radially compressible, thin-walled retainer tube open at both ends, said retainer tube is sized to receive said extension tube, secured to an adhesive-backed strip that is affixable to an outer wall of said can, said thin retainer tube walls being compressible to deform said tube from circular in cross section to oval in cross section when secured to said outer wall of said can by said adhesive strip so that the minor axis of said oval is less than the outer diameter of said extension tube to permit gripping said extension tube for storage in said retainer tube by virtue of its compression to an oval cross-section, when said extension tube is not attached to the connector. 4. An improved aerosol spray delivery system as in claim 1 wherein said extension tube includes an outer end region selected from straight, fan-shaped and curved to accommodate targeted delivery of a selected shape of product spray to a variety of surfaces. 5. An improved aerosol spray delivery system as in claim 1 which includes a spray volume limiter comprising at least one generally C-shaped shim that is removably introduced between a bottom end of said button and said dome top rolled edge, said shim having arms defining a C-shaped opening that provides a gap slightly less than the diameter of an aerosol can valve or button stem to prevent said limiter shim from falling off said stem, said limiter shim having a flexibility that allows said limiter shim to snap over the stem, said limiter shim arms are wide and long enough to bridge the entire valve assembly from side to side of said rolled inner edge of said dome, and said shim is thinner than the distance between said bottom of the button and said dome top rolled edge to permit a predetermined, limited amount of vertical movement of the button thereby controlling the volume of product flow through said valve when said button is actuated and reducing overspray. 6. An improved aerosol spray delivery system as in claim 5 which said limiter shims are of selectively different thicknesses or have flexibility to offer a range of product flow controls. 7. An improved aerosol spray delivery system as in claim 1 wherein the length of the extension tube is in the range of from about 6" to about 18". 8. An improved valve button for an aerosol can spray delivery system as in claim 1 wherein said connector tubes range in length from about ⅜" to about 1". 9. An accessory kit for an aerosol can spray delivery system comprising: a) at least one improved replacement actuator spray button of claim 1 that is permanently fitted with a short connector tube of length from about 쩌" to about 2" with a metered orifice at one end of said connector tube to produce product in spray form; b) at least one extension tube straw that is belled and flared at a first, inner end to receivingly engage and be securely retained by said connector tube, and that does not have at a second, outer end a restricted orifice therein and which conveys the product spray produced in said connector tube to a target with reduction in overspray; c) a sealing tip cap; d) at least one C-shaped spray volume limiter shim insertable between the bottom of said actuator spray button and a rolled edge of an aerosol can, said limiter shim having arms defining a C-shaped opening that provides a gap slightly less than the diameter of an aerosol can valve or button stem to prevent said limiter shim from falling off said stem, said limiter shim having a flexibility that allows said limiter shim to snap over the stem, said limiter shim arms are wide and long enough to bridges the entire valve assembly from side to side of said rolled inner edge of said dome, and said limiter shim is thinner than the distance between said bottom of the button and said dome top rolled edge to permit a predetermined, limited amount of vertical movement of the button thereby controlling the volume of product flow through said valve when said button is actuated and reducing overspray; and e) a thin-walled, radially deformable tube having both ends open as an extension tube keeper system to attach to the wall of said can. 10. An accessory kit for an aerosol can spray delivery system as in claim 9 which includes two or more: a) buttons, including at least one male and one female button; b) extension tubes of different shapes, including: straight, fan-tipped and curved; or c) limiter shims of different thicknesses or have flexibility. 11. An accessory kit for an aerosol can spray delivery system as in claim 10 wherein said extension tubes range in length from about 6" to about 18". 12. An accessory kit for an aerosol can spray delivery system as in claim 10 wherein said limiter shims range in thickness from about 1/32" to about ⅛". 13. An accessory kit for an aerosol can spray delivery system as in claim 9 wherein said connector tubes range in length from about ⅜" to about 1".
